Answer 1

subtraction duh......

Answer 2

Difference of Cubes

Difference of Squares

Square of Binomial

Sum of Cubes

Answer 3

difference of cubes?

Answer 4

can i ask a different question ?

Answer 5

Given a polynomial f(x), if (x + 2) is a factor, what else must be true?

Answer 6

\(\normalsize\color{black}{117 = 125 - 8}\)

\(\normalsize\color{black}{117 = 5^3 - 2^3}\)

\(\normalsize\color{black}{117 = (5-2)(5^2+(3)(5)+2^2)}\)

\(\normalsize\color{black}{117 = (5-2)(25+15+4)}\)

\(\normalsize\color{black}{117 = (3)(44)}\)

\(\normalsize\color{black}{117 = 132}\)

LOL, where is the mistake ?

Answer 7

your options for the next question?

Answer 8

what in the heck?

Answer 9

IT is certainly true that there is another factor and it involves a variable

Answer 10

how did you do it sooo fast?

Answer 11

f(0) = 2

f(0) = -2

f(2) = 0

f(-2) = 0

Answer 12

f(x) = (x+2) × (other factor)
f(-2) = (-2+2) × (other factor)
f(-2) = 0 × (other factor)
f(-2) = 0

what do you think, now ?

Answer 13

I'm not

Answer 14

Shouldn't it make sense, `I'mn't ` ?
